I have showed you "Stemless Gentian" by Priti NYC before but 'the third time is the charm'. ;)

Colour-wise it's a blurple which looks quite like black in shadows, more like a true purple with sunlight and like a purple with a hint of blue during daylight. It's absolutely glossy without a top coat! Two layers and it's opaque. The application is good (I don't like the brush) and the drying time is wonderful as well.
